SPRING. susr'n NsmN'ron vnnrcrns.

pension device of a novel construction and "which is hung or carried, on any desired part of the vehicle, usually on the ordinary lami= nated or leaf springs, said device being provided with a movable member mounted and :controlled between vertical springs, one or more of which s orare put in CQIIIPI'BSSIOII,

and one or more of which is or are put in tension; This spring suspension device may be applied at any suitable point on a motor vehicle, for exam le one such spring suspension device may e hung at or toward the rear end of the ordinary laminated spring at each side of the rear of the vehicle, and

if desired one such spring suspension device may be hung at or toward'th rear end of the ordinary spring ateach side of the front of the vehicle.

Reference is bad to the accompanying drawings, in which the same parts are indi cated by similar reference symbols through the several views.

- Figure- 1 is a side elevation of my invenattaching same on a vehicle; and Fig. 2 is a perspectivh view of the same.

'h A are two vertically slotted .tout frames forming oppositely disposed parallel vertical guideways A A these two frames being 7 tical giudeways and connected to one oftwo.

connected together across the top by the stout'bolt B which passes through the tubular end Y of the laminated spring by which means the spring tension device thereby supported on the end of the laminatcd spring Y. At the upper end of these stout frames A they are provided with lugs or lateral extensions A to eachof which there is attached the upper end of a tension spring C, four such tension springs being employed in this arrangement viz. two on each side as shown.

There-a r part of the vehicle body. (at each I side) is attached by means of the tubular Specification of Letters Patent.

. thefollowing claims.

Patented Oct. 20, 19141 end Z to a semi-elliptical spring Z (or it may be the end of the dumb iron) having passed therethrough the pin D fixed in the oppositely dlsposed slides E guided and formed, andarranged to slide in'lthe guide Way A These oppositely dis osed sliding members E are attached togeth er by means of, orhave passed therethrough at a lowe point, the cross pin or tie E theend 0 which pin E on' each side is journaled or otherwise fixed" in or to the sliding'c'ross" head or cross piece F- provided with lugs. or lateral extensions FF which latter thro'ii'h the medium of.the adjustable screw shack es or couplings have the lower end of the spring 0 therplpy attached thereto in an adustable manner as will be readily seen from the drawmgs.

- The lower end of each stout frame A is' provided with the lateral extension A forming a support upon which is carried the spring H located between said bottom support A and the sliding cross head F.

It will thus be seen-that the rear part of 1 the vehicle thus mounted or suspended on the vertical sliding member (formed of the parts E F D and E 0f the spring" device located at each sideof the rear part of the vehicle will in operation cause the upper springs G to be put in tension and the lower springs H to be put in compression the result bemgthat a very advantageous spring action 1s. obtamed without causing or permitting.

any lateral play or rolling action of the body.of the vehicle.

I have illustrated and described preferred tion showing the method of mounting and ."and satisfactory constructions, but obvious changes could be made within the scope of What I claim is:-' I 1. in a spring suspension forvehicles, the combination of a frameprovid'eimith verrelatively movable elements of a vehicle,

lugs projecting from the upper portion of said frame, a cross-head mounted to slide in the guid'eways in said frame and connected to the other of said vehicle elements, a cap-plate on said cross-head, a bed-plate on said frame, a coil spring arranged between said: plates, lugs projecting from said cap pl te, springs arranged between the lugs on said frame and cap plate, and means for regulating the tension of said springs.

2. In a spring suspension for vehicles, the

combination of a main frame comprising a y pair of side frames provided with vertically running guideways, means for uniting said frames in spaced relation and for connecting the same to one of, two relatively-movable elements of a vehicle, lugs projecting horizontally from either side of the top of said frame, a. bed-plate formed on each of said side frames at the base thereof, a cross head mounted to slide in the guideways in each of said frames, means for connecting said cross heads to move in unison and for connecting the same to the other of said vehicle elements, a cap-plate on each of said cross heads in Vertical alinement With the bed-plates on said frames, coil springs arranged betweemsaid plates, lugs projecting horizontally from either side of said cap plates in vertical alinement with the-lugs on said frames, tension springs arranged between said verticallyalining pairs of lugs, and means associated with the lower pairs of lugs for adjusting the tension of said springs.

3. The combination of a vehicle axle spring and a chassis spring, of a spring susension com risin a air of side frames D provided With vertically alining guideways, perforated bosses formed at the up perends of said frames, a bolt passing through the alined perforations in said bosses for connecting said side frames together in spaced relation and adapted to be mounted on the free end of said axle spring, pairs of lugs projecting horizontally from said bosses, a cross head mounted to slide in the guideways in each of said frames, a bolt for connecting said cross heads at their lower ends to move in unison, a bolt arranged bctwcen said cross heads at their upper ends andadapted to be connected to said chassis spring, a bed plate projecting horizontally from the lower, end of each of said side frames, av cap plate projecting from each of said cross heads in vertical alinement with said bed plates, coil springs arranged between said plates, a pair of perforated lugs projecting horizontally from each of said cap plates and in vertical alinement with the respective lugs on said bosses, tension springs secured at their up per ends in said first-named lugs, couplings carried by the lower ends of said tension springs and provided With threaded shanks projecting through the perforations in the second-named bosses, and nuts on said shanks for adjusting the tension of said springs.

In witness whereof. I have hereunto set my hand in the presence of two witnesses.
